What is the diameter of a hemisphere with a volume of 4960\text{ m}^3,4960 m 3 , to the nearest tenth of a meter?

Answer:

Step-by-step explanation:

Q = 7m + 3n,

R = 11 - 2m,

S = n + 5,

T = -m - 3n + 8.

R - S + T = 11 - 2m - (n + 5) + (-m - 3n + 8)

R - S + T = 11 - 2m - n - 5 - m - 3n + 8

R - S + T = 14 - 3m - 4n

R - S + T = -3m - 4n + 14

Step-by-step explanation:

The value of the expression is 256.

Simplification of an expression is the process of writing an expression in the most efficient and compact form without affecting the value of the original expression. It involves, multiply out the brackets and then simplify the resulting expression by collecting the like terms.

For the given situation,

The expression is  $x^{6} + (y^{2} \div z^3)\cdot w^3$

⇒ \(x^{6}(\frac{y^{2} }{z^{3} } )(w^{3} )\)

Substitute $x=2$, $y=3^2$ = 9$, $z=3$, and $w=4$,

⇒ \(2^{6}(\frac{9^{2} }{3^{3} } )(4^{3} )\)

⇒ \(64+(\frac{81}{27} )(64)\)

⇒ \(64+(3)(64)\)

⇒ \(64+192\)

⇒ \(256\)

Hence we can conclude that the value of the expression is 256.

Rounding up to the nearest integer, we get a sample size of 1068. Therefore, the answer is 1068.

To find the required sample size, we need to use the formula for the margin of error of a proportion:

Margin of error = z*sqrt(p(1-p)/n)

where z is the z-score for the desired level of confidence, p is the estimated proportion, and n is the sample size.

Since we want the confidence interval to have a width of 0.06, the margin of error should be 0.03. Also, since the scientists believe that about half of all people with the blood disorder will benefit from the drug, we can estimate p as 0.5. Finally, we can use a z-score of 1.96 for a 95% confidence interval.

Substituting these values into the formula, we get:

0.03 = 1.96sqrt(0.5(1-0.5)/n)

Solving for n, we get:

n = (1.96/0.03)^20.5(1-0.5) = 1067.11

Rounding up to the nearest integer, we get a sample size of 1068. Therefore, the answer is 1068.

If a stick of length 60 inches is measured to be 63 inches long the the percent error will be 5% .

The Percent Error can be calculated by the formula

Percent Error = (measured value - actual value)/(actual value)  ×100

In the question ,

it is given that

the original length of the stick is 60 inches .

the measured length of the stick is 63 inches .

So, the measured value = 63 inches ,

actual value = 60 inches .

Substituting the measured values and actual value in the percent error formula , we get

Percent Error = (63-60)/60 × 100

= 3/60 × 100

= 1/20 × 100

= 100/20

= 5 %

Therefore , if a stick of length 60 inches is measured to be 63 inches long the the percent error will be 5% .

Two-tailed because there is no predicted direction of the difference. The correct answer is D.

In hypothesis testing, a one-tailed test is used when the researcher has a specific prediction about the direction of the effect. They expect the results to be either greater than or less than a certain value. However, in this scenario, the researcher simply wants to investigate whether the new type of exercise improves people's health without any specific directional prediction.

A two-tailed test is appropriate when the researcher wants to determine if there is a significant difference between the groups being compared, but without specifying the direction of the difference. In this case, the researcher wants to examine if the new exercise has any effect on health, whether it improves or worsens it. Therefore, a two-tailed test is suitable as it allows for the possibility of observing a significant difference in either direction.

Therefore, considering these factors, the researcher should conduct a two-tailed test to assess the potential impact of the new exercise on people's health. The correct answer is D.

If \(y=x^m\) is a solution to the ODE

\(x^2 y'' - 7xy' + 15y = 0\)

then substituting \(y\) and its derivatives

\(y' = mx^{m-1} \text{ and } y'' = m(m-1)x^{m-2}\)

gives

\(m(m-1)x^2x^{m-2} - 7mxx^{m-1} + 15x^m = 0\)

\(m(m-1)x^{m} - 7mx^{m} + 15x^m = 0\)

\((m(m-1) - 7m + 15)x^{m} = 0\)

We ignore the trivial case of \(y=x^m=0\). Solve for \(m\).

\(m(m-1) - 7m + 15 = 0\)

\(m^2 - 8m + 15 = 0\)

\((m - 3) (m - 5) = 0\)

\(\implies \boxed{m=3} \text{ or } \boxed{m=5}\)

The equation of the tangent line to the curve \(e^y sin(ry) = e\)

at the point (0,1) is y = 1

To find the equation of the tangent line to the curve \(e^y sin(ry) = e\)

at the point (0,1),

we can use the following steps:

. Take the natural logarithm of both sides of the equation to get:

\(ln(e^y sin(ry)) = ln(e)\)

. Use the product rule of logarithms to simplify the left-hand side:

\(ln(e^y) + ln(sin(ry))\) = 1

\(y + ln(sin(ry)) = 1\)

. Take the derivative of both sides of the equation with respect to x,

using the chain rule for the second term on the left-hand side:

\(d/dx\) \((y + ln(sin(ry))) = d/dx(1)\)

\(dy/dx\) +\(cos(ry) dy/dxr\) = 0

\(dy/dx\) \((1 + cos(ry)*r)\) = 0

\(dy/dx\) = 0 when r \(= -1/cos(y)\)

. At the point (0,1), we have r\(=\) \(-1/cos(0) = -1.\)

. Finally, we can use the point-slope form of the equation of a line to write the equation of the tangent line:

\(y - y1 = m(x - x1)\)

. where \((x1, y1)\) = (0, 1) and m = \(dy/dx\)= 0

when r = \(-1/cos(y) = -1\)

\(y - 1 = 0(x - 0)\)

\(y = 1\)

Therefore, the equation of the tangent line to the curve \(e^y sin(ry) = e\)

at the point (0,1) is y = 1.

In classification analysis, we are determining the probability of an observation belonging to a specific class.

Classification analysis is a machine learning technique used to predict the class or category to which an observation belongs. The goal is to assign a probability to each possible class, indicating the likelihood of the observation belonging to that class. This is typically done by training a classification model on a labeled dataset, where the classes are known for a set of observations. The model learns patterns and relationships from the training data and then uses that knowledge to predict the class of new, unseen observations. The predicted probabilities can be used to make informed decisions, such as determining the most likely class for a given observation or setting a threshold for making binary decisions.
